Wow Paul and Donald! this is all just fantastic stuff for me! thank you
thank you so much to both of you for your kind energies and efforts, and for
providing invaluable example code here for me of these function usages.
There's lots here I've never used, and it sounds like it'd be helpful for
me to get to grips with all of this.
What I've done today is firstly try Paul's approach, since I recieved it
first.
After some time, ... ok a lot of time, diddling with this, what it appears
to me like is happening is,
The GetTextInRect function I'm using to grab blocks of data from the screen,
seems to me, somehow, to be actually AutoConverting the "\9" tab characters,
to spaces in my string! Before the
StringReplaceSubstrings function gets time to do it's stuff.
So that by the time it does, there's no tabs left in the string to be found!
is that possible? probible?
Then, I thought that perhaps this GetTextInRect function, upon only
recieving the 4 parameters of Left, top, right, and bottom, might feel it
was being given permission to strip out Tabs automatically, because I wasn't
asking it to keep lineBreaks as a whole block.
But that's not it either, as when I fill in all 8 of the parameters,
including a 1 at the end to retain LineBreaks, it still doesn't seem to
work.
So, when I follow Paul's logic, By the way I never ever knew that the tab
character had a value of "\9", nor that spaces had one of "\32" before,
But, thanks to this great coding help,
I do now!
so, as I say when I use paul's logic, and insert the word "Blonk. " in
quotes where he previously had coded a period character, as I'd indicated I
desired,
just to make things reeeally clear to me,
when I replace "\9", with "\32", like this:
(Oh I've also altered Paul's example stringCode names a bit as well to suit,
;let sAnnouncePromptsWithPauses = StringReplaceSubstrings
(sFunctionKeyPrompts, "\32", "Blonk. ")
It's putting the word "Blonk" in my resultant string every single place it
sees not only a space, (which of course appears sometimes between the
wordings of the function Key options themselves, so is obviously quite
non-optimal,
but also whenever it sees the Tab delimiters!
Which is just so weird!
So it thinks they're spaces too!
Has anyone ever encountered this before, and/or have any way around it such
that the string gathering retains the tabs, with their character value of
"\9", as is?
I've just tested GetTextInFrame, and it does exactly the same thing!
ooooh man! I've just clarified this even more, by discovering that when I
use a GetLine instead, then Paul's logic works a treat! and the tabs or "\9"
characters, seem to indeed be retained in the string, and thus found by the
StringReplaceSubstrings, function!
So one wonders now, why on earth would certain stringGathering functions
feel it their duty/ungiven permission, to treat Tabs as spaces!
<sigh.>
So I guess I'll have to do reeeeally crude and slow stuf like Routing jaws
Cursor to certain spots and doing GetLine, nextLine, GetLine stuff, which is
just sooo inelegant!
Any thoughts anyone?
